Chris Hunt 3f9b326c11 Provide a reasonable error on invalid scheme keys ... Originally we would throw an `AttributeError` if a bad scheme key was used. After refactoring we would throw a `KeyError`, which isn't much better. Now we call out the wheel being processed, scheme key we didn't recognize, and provide a list of the valid scheme keys. This would likely be useful for people developing/testing the wheel.		2020-07-29 22:24:09 -04:00
